Rugged, invar stabilised, pulsed Nd:YAG lasers with high energy and high Performance for industrial and scientific applications.

The LPY series of pulsed lasers have been designed to suit almost any industrial or research application in which a high-energy or high-specification Nd:YAG laser is required. Based around a fully self supporting invar rail the LPY series exhibit both exceptional mechanical and thermal stability. A ‘no-compromise’ design approach is evidenced in the build quality, a parameter that sets these lasers well apart from any of their competitors.

The modular design of the laser head allows a wide variety of resonator configurations to be offered, from single rod oscillators to fully birefringence compensating twin-rod-oscillator, twin-rod amplifier systems. Furthermore, a choice of stable, stable-telescopic or unstable Gaussian-coupled resonators is available, allowing the customer to specify a system that suits their requirements.

The LPY range is comprised of three series, the LPY600, LPY700 and LPY7000 series. All utilise the same robust invar stabilised, modular construction, the differences being in the resonator and amplifier topologies.

The LPY600 lasers are oscillators or oscillator amplifier systems with a single rod in the oscillator or amplifier. These are predominantly used for low (up to 30 Hz) repetition rates and moderate power outputs.

The LPY700 lasers are oscillators and oscillator amplifiers that use a twin-rod architecture in both the oscillator and amplifier to effectively compensate for the thermally induce strain birefringence in the laser rods. Such a method leads to very high beam homogeneity (especially in the harmonic wavelengths) at high power throughputs. This allows the LPY700 series to run at up to 200 Hz with high energy outputs and extremely uniform beam profiles.

The LPY7000 lasers are ultra high output energy systems that give outputs of up to 3.5 J per pulse.

All LPY lasers can be fitted with an optional injection seeder to give SLM outputs.

Energies of up to 3.5 J and repetition rates of up to 200 Hz are standard. Applications include Dye laser pumping, OPO pumping, Spectroscopy, LIBS, LIDAR, PIV and many more.
